I have this huge book of chess problems by Polgar, but it is so big, it's
inconvenient to take it down and use it. Since I have an ereader, I
realized I could use it view chess problems in PDF files. So I did some
searching and found some good resources.
Here is a collection of mate-in-ones, targeted at kids. It should be the
easiest one to begin with:

Here are a few mate-in-two problems from the same source:

Here are pages linking to old chess problem collections now in the public
domain:
