I haven't been able to find a good English-Hebrew/Hebrew-English dictionary in e-Book format, but this dictionary is better than nothing.
I knew before I bought it that its Hebrew entries were romanized and didn't use the Hebrew alphabet. That's not great.
What I didn't know was that it also lacked a table of contents with links to the section for each letter. If you want to look up a word that starts with the letter 'M', you either have to search for the word (hoping you spell it exactly as the e-Book does) or page manually from A to B to C ... to M, which is tedious and time-consuming.
It would have killed them to include a linked table of contents? I've done it and it takes about 10 minutes, tops.
Like I said, this dictionary is better than nothing.
I look forward to the day when a really good English-Hebrew/Hebrew-English dictionary becomes available as an e-Book.
