This method is used for cataloguing multi-part monographic resources, where individual parts do not have their own title (see example 1) or have relatively unimportant subordinate titles that can be a substitute for numbering (e.g. a letter sequence if the contents is in an alphabetical order, as for lexicons, dictionaries, registers etc.).

If each part has its own ISBN, the field 010 – International Standard Book Number is repeated, and the appropriate part number is entered in subfield 010b – Qualification. A common ISBN is also entered if exists.

If you download the record for the multi-part monographic resource of the group A from the shared database, the data concerning parts, which is not available in your library should not be deleted. The parts that are actually available in the library should be indicated in the holdings data (see example 2).

With this method you can catalogue resources, for which the publication is already completed (see examples 3 and 4).

If the publication was not completed in one calendar year, enter the code "g" – monograph whose publication continues for more than one year in the subfield 100b – Type of publication date, the year of the first published part in the subfield 100c – Publication date 1 and the year of the last published part in the subfield 100d – Publication date 2.

If the publication of multi-part monograph resources was completed in one calendar year, enter the code "d" – monograph complete when issued, or issued within one calendar year in the subfield 100b and enter the publication year in the subfield 100c.

According to the field 100 – General processing data you also need to enter the subfield 210d – Date of publication, distribution, etc., formulated like so: "first publication date–last publication date".

The number of parts should be entered in subfield 215a – Specific material designation. If individual parts do not have subordinate titles and if all parts are published in the same year or if two parts are published in succession (the first part and then the last part), enter the pagination of individual parts in the subfield 215a.

If the individual parts have subordinate titles or if all parts are not published in the same year or in a specific order, enter the pagination of individual parts in the field 327 – Contents note.

The titles of individual parts should be entered in repeatable subfields 327a – Text of note. The introductory phrase and a colon ("Contents:") should be entered in the subfield 3270 – Introductory phrase and the designations and titles of individual parts as well as other data (e.g. the publication year, pagination, responsibility etc.) should be entered in the subfield 327a. In order for the contents of each subfield 327a to be displayed in its own line, the indicator 2 in the field 327 should have the value "1" – Repeated subfields a are separated by a new line.

With this method you can catalogue resources which are not yet published (see examples 5, 6 and 7). When the library receives a new part, you update the record (see example 2).

In the subfield 100b the code "g" should be entered. Enter the first publishing year in the subfield 100c. Enter "9999" in the subfield 100d, if there is only one part published or if all parts until now were published in the same year. Otherwise enter a publication year of the temporary last part (see example 5).

According to the data in the field 100 enter also the subfield 210d in the form of "YYYY-" if there is only one part published or multiple parts in the first year or in the form of "YYYY-<YYYY>" (the second year indicates the publishing year of the last published part), if the parts are published during several years.

In the subfield 215a enter the current number of parts in angle brackets.

When each subsequent part is published, change data relating to the publication year of the temporary last part in the subfields 100d and 210d, as well as the number of issues in the subfield 215a. The code "g" in the subfield 100b remains the same, even after the last part is published, unless all parts are published in the same year. In such case, replace the code "g" in the subfield 100b with the code "d" after the last part has been published.

Enter the titles of individual parts in the repeatable subfields 327a. Enter the introductory phrase and a colon ("Incomplete contents:") in the subfield 3270 and enter the designations and titles of individual parts as well as other data (the publication year, pagination, responsibility etc.) in the subfields 327a. The first indicator in the field 327 should have the value "0" – Contents note is not complete. In order to have the contents of each repeatable subfield 327a displayed in a separate line, the second indicator in the field 327 should have the value "1". You enter field 327 each time when a new part is published.

The data relating to the individual parts in fields 215 and 327 are supplemented in the numbering order and not in the order they come into the library. When the last part is published the monographic resource is complete. At that time you supplement the record according to the rules in the previous chapter.

For multi-part monographic resources from the group B you download from the shared database only records for parts that exist in the library. If records are created, each part should be assigned its own bibliographic record.

With this method you can catalogue multi-part monographic resources, where each individual part has a common title as well as a subordinate title (see example 8).

In the record for an individual part you enter the data about the part being described. The common title is entered in the subfield 200a – Title proper, the number of the part in the subfield 200h – Number of part and the title of the individual part in the subfield 200i – Name of part.

If there are more levels of subordination, repeat the subfield 200i (see example 9) or the subfields 200h and 200i.

With this method you can catalogue multi-part monographic resources, where each individual part contains more works, and the title page includes the common title and the titles of individual works (see example 10).

Enter the data for the described part in the record for an individual part.

Enter the common title in the subfield 200a and the number of the part in the subfield 200h.

Because the titles of the works, contained by individual part, are equal they should not be entered in the repeatable subfields 200i (this would mean they are in a hierarchical relationship).

Equivalent titles of individual works should be entered in the field 327. Enter the introductory phrase and a colon ("Contents on title page:") in the subfield 0. If the works are by one author only (who is entered in the subfield 200f), enter these titles in the repeatable subfields a. The indicator 2 should have the value "0", so that the punctuation (semicolon) is automatically displayed between repeated subfields a or between equivalent titles. Titles of works by different authors or of anonymous works are also entered in repeatable subfields a. Indicator 2 should have the value "2" so that the punctuation (point) is automatically displayed between repeated subfields a or between equivalent titles.

The titles of individual works and their authors should also be entered in the field 423 – Issued with.

In multi-part monographic resources of the group C you can create a common record for all parts and you can also create records for individual parts. The libraries choose which method to use based on their needs. If the record (records) for a multi-part monographic resource is already catalogued in the COBIB database in one way and the library wants to catalogue the resource in another way, they cannot change the existing record (records), but they need to create a new record (records) using a different method.

This means that records, created with both methods, can coexist in COBIB and local databases.

There are two ways to catalogue multi-part monographic resources, which have a generic expression for the common title (e.g. "Zbrana dela", "Collected works", "Gesamtwerke", "Gesamtausgabe"...), and where the title page also includes titles of works in an individual part. Titles are at the same hierarchical level (see examples 11 and 12).

If you are creating a common record, you describe individual parts in the contents note in the field 327. This method enables a broad overview, which is especially important for the national bibliography. For search purposes titles with meaning are also entered in the field 423. Titles comprised from generic expressions can be omitted in the field 423.

If you create a record for each part, you enter the titles of individual parts into the repeatable subfields 200a. You enter the common title, statement of responsibility and the number designation of the part in the field 225 – Series (in the corresponding subfields 225afv). For the purposes of searching by title it is also recommended to enter the common title in the subfield 540a – Additional title.

There are also two methods for processing multi-part monographic resources, when the subordinate titles of individual parts express some kind of a sequence, for example a time span, historical periods etc. (see example 13).

You can create one bibliographic record and describe individual parts in the contents note in the field 327. This method enables a broad overview, which is especially important for the national bibliography. For search purposes the titles of individual works are also entered in the field 423.

The library can create separated records for individual parts for different reasons (e.g. for the purpose of an appropriate display of the personal bibliography).
