The On-Line Encyclopedia of Integer Sequences (OEIS) is a database of number sequences that enables users to check if a sequence that has arisen in their work has been studied by others. A typical entry gives the first 50 or so terms of the sequence, formulae, references, links, computer programs for producing the sequence, etc. To find the OEIS, Google "sequences".
The OEIS contains over 110,000 sequences and gets over 20,000 hits per day. Over a thousand new sequences are added each month. This talk will describe some of the most interesting sequences received in the past few months, including some that are defined by very unusual recurrences. Many open problems will be mentioned.
