When you are ready to scan,
you will need to decide whether you plan on scanning the
documents as images or with Optical Character Recognition
(OCR). The advantage of OCR is that documents are
converted to an editable format, which is useful if they
are documents you want to alter. If you are scanning
your documents with OCR, save the files in the format of
whatever application you will be using to edit them.
However, if you are creating an archive you most likely
want to maintain the integrity of the records you are preserving,
in which case you should scan them as images.
Scan the documents at a size
and resolution that will make them useful to you in the
future. Keeping in mind that you may have to print
them out some day, it is probably a good idea to have a
minimum resolution of 150 ppi, though 300 ppi might
be better for documents with especially fine print.
Scan them at the actual dimension of the object in order
to be able to reproduce it accurately if needed. Don’t
forget to scan both front and back.
If you are saving your documents
as images, you have several choices for file formats.
Bitmap (.bmp) is the native image format for the Windows
operating system, and will provide images of high quality.
Tagged Image File Format (TIFF) are also very detailed,
and unlike the bitmap file format, it’s supported across
most operating systems. However, both bitmap and tiff
files are very large; if you choose to save your archive
in one of these formats, it will take more disk space to
do so. Alternatively, you could save your files in
the Joint Photographic Experts Group (JPEG) format, which
compresses the data somewhat, but is generally sufficient
for most uses.
storing
When you’ve finished scanning
your documents, you’re ready to transfer them to a storage
device. Ideally, you will be able to save them to
CD, because they have the highest storage capacity and can
be read by nearly any computer. However, Zip disks
and even floppies will work just as well if that is all
you have available.
Create clearly labelled folders
on your disk in which to store the files you have created.
And, when you have completed transferring the files to the
disk, be sure to label the disk and it’s case too.
Spend a little extra time now making sure everything is
properly marked, instead of spending a lot of time later
when it’s time to dig it out. If you’re saving especially
important information, make a copy of the disk and keep
it in a separate location from the original, such as a safety
deposit box or safe, to protect your records from theft
or disaster.
It can be confusing to know,
sometimes, how long you need to retain the records you have
saved. Some tax records, for example, only need to
be kept three years, while for others it is four, and some
should be kept forever. By transferring your records
to a digital archive, you can keep your records indefinitely
without having to give up a lot of space to do so.
