I noticed that lastchecked and URL are non-standard attributes for a bibTeX files, which is kind of strange nowadays, but that's a different matter.

I tried to use @misc{...} with itmalpha style, but my document doesn't show the two attributes. Which style can I use for it to display, which doesn't mess up my other references, which are articles and incollections (for now).

In most bibtex styles the information about url and the date when the web page has been accessed can be stored in the howpublished field (in free format).

A second alternative is to modify the itmalpha style to accommodate the two fields. The styles does not support url and lastchecked. Thus the first step is to insert these two fields in the ENTRY part of the style:

ENTRY

  { address

    ...

    lastchecked

    url

    ...

  }

  {}

  { label extra.label sort.label }

Then, we create a function to print the value of the fields. Thus we insert the following code in the file

FUNCTION {format.url.lastchecked}

{

  url empty$

    'skip$

    { "Available at: url{" url * "}" * 

      lastchecked empty$

        'skip$

        { "Accessed on: "  lastchecked * }

      if$

    }

  if$

}

Finally, we have to use the function at the appropriate position (in the definition of misc). We can replace the definition of misc with

FUNCTION {misc}

{ output.bibitem

  author empty$                               % added by R.Bless

    { format.editors output.nonnull }          % added by R.Bless

    { format.authors "author" output.check }   % added by R.Bless

  if$

  title howpublished new.block.checkb

  format.title output

  howpublished new.block.checka

  howpublished output

  organization output

  institution output

  format.date output

  fin.entry

  format.url.lastchecked output

  new.block

  note output

  fin.entry

  empty.misc.check

}

Instead of editing the itmalpha.sty file, please make a copy, edit it, and rename it (e.g. myitmalpha.sty).

PS I have used url{} to wrap the value of the bibtex url field, this requires to load an appropriate style, e.g., url or hyperref.

all styles here http://archiv.dante.de/~herbert/Bibliography/ know the fields url and urldate
