I went to here:
http://wiki.logos.com/Example_Collections
But I can't see how to exclude Perseus. The example gives:
English Library without Perseus
- Library Size: 4,096
- Collection Size: 1,889 Excludes 825 Perseus
- Rule:
- Manually Included Items: {Language:English}
- Manually Excluded Items: {Perseus}
What does that mean? There is no 'rule' I can copy and paste. Searches on how to manually exclude something come up blank. You can minus something by dropping it in the box, but how do I set up a collection so that I can search the library without searching Perseus?
