Nebraska has two codes - one official, one unofficial. Bound volumes are reissued when there is too much new law and too many annotations to fit comfortably in a supplement. There is no particular schedule for reissue volumes, and bound volumes are not reissued at the same time. So, you must make sure you are using the most recent reissue volume. Make sure your volume reissue date is the same or more recent than the date indicated in the table.
Volume is current.
Volume is not current. You must make sure your statute is still current law. To do this, you must update your statute beyond the bound reissue volume by using the most current supplements. In even-numbered years, the supplement is cumulative. In odd-numbered years, the supplement is annual, and not cumulative.
