  Bounds on the Minimum Distance of Linear Codes http://www.win.tue.nl/~aeb/voorlincod.html
Fill in q, n, k, and get bounds on the maximal minimum distance of the linear codes over GF(q) with length n and dimension k.
  Constant Weight Binary Codes http://www.research.att.com/~njas/codes/Andw/
Lower bounds (and in some cases exact values) for A(n,d,w), the size of the largest binary code of length n, distance d and constant weight w.
  Optimal One-Error-Correcting Codes http://www.tcs.hut.fi/~pat/72.html
Optimal binary one-error-correcting codes of length 10 have 72 codewords. Tables to supplement the paper published in IEEE-IT 45 by P.R.J. Östergård, T. Baicheva and E. Kolev.
  Check or Generator Matrices of Some Linear Codes http://www.mathi.uni-heidelberg.de/~yves/Matritzen/Codes/CodeMatIndex.html
Examples for q up to 9.
  Database on Binary Quasi-Cyclic Codes http://www.tec.hkr.se/~chen/research/codes/searchqc2.htm
Interactive page to find the code parameters (generator polynomials and weight distribution) and references.

Database of information on binary linear codes of length n and dimension k with n <= 85 or n <= 204 and k <= 14. Searchable.
  Tables of Binary Block Codes http://webfiles.portal.chalmers.se/s2/research/kit/bounds/
Tables of bounds on the size of binary unrestricted codes, constant-weight codes, doubly-bounded-weight codes, and doubly-constant-weight codes. Compiled by Erik Agrell, Chalmers.
  Nonlinear Binary Codes http://www.research.att.com/~njas/codes/And/
Lower bounds (and in some cases exact values) for A(n,d), the size of the largest binary code of length n and minimal distance d.
  Covering Codes http://www.eng.tau.ac.il/~litsyn/tablecr/
The best known bounds on the size of binary covering codes of length up to 33 and covering radius up to 10. Compiled by Simon Litsyn.
