First, the good news! I have added full keyword searching! Now the bad news - you'll have to guess what the keywords are that I use. For example I frequently use "fecundity", "clutch size" and "reproduction" interchangeably. With a bit of imagination, and some guessing, you're likely to be able to find what you want. You can still do searches for authors, or specific words in the title. But the scope of your searches has improved at least 10-fold with the addition of keyword searches. The keywords will not show up on the output screen.

For species searches, you might be able to help yourself out by searching for the Latin name of the species you're after - works most effectively if you use the second part of the name (e.g., "bernicla" for brent or brant)

The only other thing to know is that the logical boolean "AND" or "OR" work for all the keywords in your list. In other words, if you search for "egg size temperature", and use the AND boolean, the program will return only those records which contain all 3 words. If you want to match a precise string, use the "PHRASE" boolean.
