I am trying to make a trial run at cataloging, and it's turned up information that I don't know how to populate. The book I picked up is "The Bible and Holy Fathers for Orthodox", ISBNdb entry at https://isbndb.com/book/9780962253607. Most of the entries in the catalogue will be books, with some periodicals and maybe coverage of relevant websites. I clicked on the "Books..." entry under "New entry"; that gives me a form with the following fields as required: 000 ? - LEADER 005 ? - DATE AND TIME OF LATEST TRANSACTION 008 ? - FIXED-LENGTH DATA ELEMENTS--GENERAL INFORMATION 040 ? - CATALOGING SOURCE > Transcribing agency What should I be doing to fill at least these out? Does "Z39.50/SRU search" or "Link authorities automatically" provide a way to populate from existing question? Thank you for any orientation and advice. Thanks, Br. C.S. Hayward, author and apologist, and more importantly novice at St. Demetrios Orthodox Monastery
