I recommend the Mark Twain Library editions published by Univ. of California. They're not exactly cheap, but they are attractive and include the original illustrations, which are a must. The series also has some volumes that come from manuscript material, such as the "Mysterious Stanger Manuscripts." This past year I used the Library of America volumes, especially the two collections of stories, essays, etc. I don't think I'll do that again, since I found the physical books rather dispiriting to read: they're so solid and reliable and proper, and so lacking in illustrations. There are also some Mark Twain works in the Norton Critical editions. These are nice because they have supporting material and a selection of critical articles all nicely contained for limited projects involving secondary material. The Dover Dollar editions (some of which cost two dollars) also include some Twain, but I've never looked at those to see how textually reliable they are. They certainly are cheap, however. Finally, you should get your library to acquire the recent Oxford Mark Twain, which is relatively inexpensive (for a library) and reliable and furnished with introductions and other stuff by both academics and normal people.
