Outlines of a philosophy of religion based on psychology and history / Auguste Sabatier. (OCLC #1058227)
For each series in the catalog, we may choose to trace (explicitly link resources in the series to a series authority via an authorized access point, like with MARC 830) or not trace (but maybe transcribe in a series statement/note). We often don’t trace for purely publisher-related series, like:
490 0_ ǂa Harper torchbooks ; ǂv TB23
but trace for other kinds of series, such as those where a publisher groups their titles by subject:
490 1_ ǂa The Library of religion and culture. 830 _0 ǂa Library of religion and culture.
In MARC, the decision to trace or not trace is recorded in authority field 645. Series authority records often exist to explicitly state that the decision has been made to not link to them (example).
