Multiple Worksheets For Data Entry

I currently have a spreadsheet that has a total of 20 workbooks in all. Each workbook contains between 5 and 100 rows and between 20-40 columns. Each column is a different category that I have data on for that particular tool manufacturer. What I want to do is create a front workbook where I can do all my searching. I would like the user to impute data into a search cell, hit a macro button, and have the full row that data was in be shown to them. Depending on which criteria they search for, the value may be found at the start, middle or end of the row.

Also, like I said the number of columns differs between each workbook. I would also like it to print out the categories for that workbook so that the person inputing the data knows what all the different numbers are when they come up.

Each workbook is a different tool manufacturer that my company has a tool from so there should never be duplicate data. The problem is that after I finish the spreadsheet, I am turning it over to the floor workers and they will have the ability to add/change any information in any workbook. If a mistake is made and different workbooks have the same data, I would like it to print out the category and data from the first workbook, then print the category and data from the next workbook and so on. The Category headers make up the first 2 rows of each sheet.
