Using the library catalog to look for a book and the frustration of not finding the index card you were looking for.
A catalog card is an individual entry in a library catalog containing bibliographic information, including author’s name, book title, and even approximate location (on bookshelf).
Here’s an example of a catalog card, which would be filed alphabetically in the Author section:
